There are really three separate questions here:
1. Should XeTeX accept Unicode's many space characters in the input, as
opposed to just using existing TeX commands for spacing?
2. If the answer to #1 is "yes," what exactly should be the consequences
of each space character? Grouping this under the same question because
it's related: to what extent should the font determine the width and
nature of each space character?
3. If the answer to #1 is "yes," how should this be implemented - in
particular, should it be in the engine or by macros?
It sounds like you're saying "yes" to #1 and "in the engine, not in the
macros" to #3.
Yes, I am; it does not seem to me to make sense to implement the glyphs
of Unicode without also honouring its non-glyph-contributing elements.
